Supported Applications

The Omega LVN10-20 Series comprises low-cost, vertical-mount liquid level switches designed for submersion in tanks. These devices utilize a reed switch mechanism to provide high repeatability and are sealed with potting compound specifically for moisture-laden environments.

  • Liquid Level monitoring

Operating Conditions & Performance

The series operates within an ambient/process temperature range of -40 to 82°C (-40 to 180°F), with a maximum operating limit of 110°C (230°F) in Oil. The switches are sealed to meet NEMA VI (NEMA 6 / IP68) ratings, allowing for submersion and years of worry-free operation.

  • Maximum Pressure Rating - LVN-10: 160 psi
  • Maximum Pressure Rating - LVN-20: 225 psi

Configuration Options

The series offers two primary models, LVN-10 and LVN-20, distinguished by process connection size, overall length, float dimensions, and pressure ratings. Both variants feature a SPST switch with user-selectable normally open or normally closed configurations.

  • Process Connections: 1/8" NPT (LVN-10) and 1/4" NPT (LVN-20)
  • Mounting Orientation: Vertical mount at the top or bottom of a tank
  • Electrical Connection: Lead Wires, 20 AWG, 24" PVC (-600V rating noted in dimensions table for LVN-10/LVN-20 context)

Wetted Materials and Construction

The series supports the following wetted materials: Brass, Buna-N, and 316SS. The stem material is specified as Brass.

  • LVN-10 Float Material: Buna-N (Specific Gravity: 0.56)
  • LVN-20 Float Material: Buna-N (Specific Gravity: 0.70)

Switch Ratings

The switch rating for both LVN-10 and LVN-20 is listed as 50 VA.

Key Product Differences

Differences between the two models are defined by physical dimensions, connection size, and pressure capacity:

  • LVN-10: Features a 1/8" NPT thread, an overall length of 54 NOM (2 1/8 NOM), an 11 mm HEX (7/16" HEX) hex nut, and a float dimension of 25 DIA x 25 mm H (1 DIA x 1" H).
  • LVN-20: Features a 1/4" NPT thread, an overall length of 87 NOM (3 7/16 NOM), a 14 HEX (9/16 HEX) hex nut, and a float dimension of 32 DIA x 44 H (1 1/4 DIA x 1 3/4 H).

Switch actuation occurs approximately at the halfway point of float travel or half the distance from the end of the stem to mounting.
